Beelzebuth appears as a young woman--a Siren--but little is known of her, except that she is not human and claims to have possessed her current body. She was known to associate with Georges, although the nature of their relationship is unknown.

The Warren Report states that she was thought to have been a guardian of the Palace, "as she was conversant with the forces of chaos, and liches and other undead did her bidding."

Beelzebuth encountered Denam on floors 22, 41, and 74. Her current body was destroyed during the battle on 74.
